Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is connected to its respective medical instruments by a spirally wound driving medium hose that is in a deflated state when not in use and can be expanded when in use. The present invention relates to a dental medical instrument having a handpiece and a storage stand for storing the handpiece when not in use.

These helically wound operating medium hoses (Ringer hoses) are automatically retracted by the pull-back pretension of the helically wound hoses when the handpiece is returned to the storage stand after they have been withdrawn. Such a device, which has the advantageous property of being pulled back again, is described, for example, in the Siemens company publication SI RONA, page 4, MD 1071182. l
It is known as 0IK. Here, the operating medium hose hangs freely downwards when not in use, ie when the handpiece is in the storage stand, which results in a relatively large space requirement.

These downwardly hanging hoses therefore pose an obstacle, for example, when the device is being rotated over a patient. Furthermore, the dead weight of this downwardly hanging hose weakens its pre-existing retracting tension, thus negatively impacting, and in some cases even eliminating, the above-mentioned advantage of automatically retracting the hose. I'll get lost.

The present invention has the content as described in each claim of the present patent application, and its purpose is to eliminate the above-mentioned drawbacks and eliminate the use of dental medical instruments of the type mentioned at the beginning of the main text. The object of the present invention is to create a dental medical instrument in which the drooping of the operating medium hose in the normal position is eliminated by simple means.

The advantage achieved by the invention is essentially that the hose storage pedestal constitutes a supporting means for holding the hose when not in use, so that no sagging of the hose can occur. When the handpiece is picked up from its storage position and brought to the treatment position, the pose is easily pulled out of its storage position, while this is due to its pre-applied pullback tension when the handpiece is returned to the storage position. It is automatically pulled back and takes up its position on the storage stand again.

Advantageous further aspects of the invention are listed in the respective embodiment claims and are explained below.

Embodiments of the invention are illustrated by way of example in the accompanying drawings.

The dental instrument 1 shown in the accompanying drawing is constructed in the form of a flat instrument body 2 with a table-like surface 3, which is supported by a support device 4, which is partially visible in the figure. It is attached to a dental treatment table 5.

In the rear part of this instrument body 2 there is a switching device, as shown in FIG. 2.4 and FIG. 7 is accommodated. In this case, each opening/closing device 7 is directly connected to a rear connecting piece 8 of a wound operating medium hose 9 which is in a contracted state when not in use and can be pulled out during operation.
A hand piece 6 for dental treatment is attached to each end of the hose on the patient side to be treated.

The instrument 1 further includes a storage blade 10 for storing the handpiece 6 when not in use. By grasping the dental handpiece 6 and pulling out the operating medium hose 9, the corresponding switching device 7 is moved vertically, not shown, into the operating position, while the other switching device 7 is moved into the operating position, as shown in the figure. It remains in the position when not in use. When the hand piece 6 is returned to its original position, the hose 9 is pulled back again and the corresponding opening/closing device 7 is returned to its tilted position when not in use.

The device 1 is provided with hose storage means 11 for use when the operating medium hose 9 is not in use. This hose storage means 1
1 prevents the hose 9 from hanging down when not in use, this hose storage means 11

As shown in FIGS. 1 and 2, the mounting plate 13 or 13t
The front end of the hose 9 in the drawing direction of the hose 9 is formed as a groove-shaped handpiece storage member 10, respectively.

In FIGS. 5 and 6, the hose storage means 11 is located inside the instrument body 2, and in the first to stripes 4 it is located at a distance below the instrument body 2. In this case, the hose storage means 1 is fixed to the instrument body 2 by a hanger 15.

In the embodiments shown in FIGS. 4 to 6, the configuration is as follows: one or more storage units 14 are configured in the form of an L, spaced apart from each other. The horizontal part of the medical device is formed by a hose hook 16 which is oriented in the direction of retraction of the hose 9 to receive the spirally wound hose, and these are connected by means of its L-shaped vertical part forming the hanger 15. is fixed. In the embodiment shown in FIGS. 5 and 6, the hose hooks 16 provided inside the device body 2 are provided for the individual hoses 9 in the device body 2 in the direction in which these hoses are drawn. and is provided in each hose chamber 17 that is open downward. Furthermore, in FIGS. 4 to 6, each of the hose hooks 16 is provided with a knotted bead storage member 10, which is formed in the form of a notch 18 and is connected to the longitudinal extension line of the hose hook. The hose 9 can be pivoted in the direction of the arrow 19 about a horizontal axis extending laterally, ie transversely to the retraction direction of the hose 9.

In the embodiment shown in FIGS. 5 and 6, the separate handpiece storage member 10 is located at the hose 9 of the instrument body 1.
Each hose chamber 17 is located on the side facing the direction of retraction.
is placed above.

An essentially vertically extending hanger 1 of the hose storage means 1 as shown for the embodiments of FIGS. 1 and 3.
5 is movably supported by the instrument body 2 at its upper end.

For this purpose, on the one hand, the upper end of the hanger is supported in the device body 2 so as to be rotatable in the direction of the arrow 20 about a horizontal axis B extending transversely to the direction of inlet of the hose; on the other hand, is supported in the instrument body 2 so as to be reciprocating in the direction in which the hose 9 is drawn in, ie in the direction of the arrow 21. Furthermore, the upper end of this hanger is supported on a slide member 23 which is reciprocatable in the guide rail 22 with the axis B mentioned above. Furthermore, the third
In the figure, the hanger 15 is attached to the shaft rod 24 having the above-mentioned axis B.
A stop member 25 is provided for fixing the hanger in an inclined position, and in order to form the stop member 25 on the shaft 24 at that time, an annular corrugated shape, for example, is provided between the upper end of the hanger and the lock nut 26. A compression spring 27, such as a spring, is provided.

2 and 3, the above-mentioned slide member 23 is arranged in the guide rail 22 so as to be able to reciprocate in one or more mating stop positions. For the formation of the guide rail 22 on the one hand and on the other hand in the slide member 23 cooperating stop means 28, 29 are provided. These stop means are arranged on the one hand in a recess 2;
8 and, on the other hand, a stop horn 9 member 29, such as a stopper pole, which can be fitted into this recess by means of a spring.

Furthermore, as can be seen from FIGS. 2 and 3, the guide rail 22 has a U-shaped cross section and the recesses 28 are provided on the inner surfaces of its side walls 30, with the struts 4? The member 29 is provided on the slide member 23. In this case, the stop member 29 is located at the lateral cutout 9 of the slide member 23.
The stopper member 2 is supported within the portion 3.
A pressure spring 32 is provided which presses the guide rail 9 into the recess 28 of the guide rail 22. The sliding member 23 has a sliding shoe 33 at its lower end for sliding movement within the guide rail 22;
It has stop means 29 cooperating with stop means 28 of.

In this case, the sliding member 23 is inserted into the upper groove 34 of the sliding shoe 33 and is secured by at least one connecting pin 35. This connecting pin 35
passes laterally through the slide member 23 and is inserted from the inside into a lateral cut-out 31 whose tip is provided in the slide shoe 33 and has the pressure spring 32 and the stop horn member 29. It is embedded.
